Munitions Building, Washington, D.C.

June 14, 1937

My dear students, you have brilliantly succeeded

in deciphering the various Kryha messages I had

prepared for you. Before moving on to the longer

messages, I propose a rather unusual Problem.

At first glance, I don't think you'll be able to

decipher it. Indeed, I'm not giving you any

information: not the stops, not the period, not the

alphabets ! Moreover, the message is very short!

The only help: the probable word "lieutenant".

This problem is designed to confront you with

failure and teach you to limit your efforts in

the face of the impossible. I was inspired by a

naval wargame called the Kobayashi Maru, which

was designed to make the student fail.

Frank B. Rowlett.
